On objections to voter ID

Regarding voter ID laws, one common objection is that it would disenfranchise people who do not have a drivers license, other state issued ID, or passport.  OK, so let's think this through; you cannot get a job, be in the military, fly in a plane, get a loan or credit card, buy or rent a decent home, and a lot more with out one of these IDs.  Now I know that we view ourselves as a Democracy where everyone gets to vote, but do we really want people this disconnected with our society to vote?    Do you want someone who has never held an honest job to be formulating economic policy, for example? 


In the same way, are we doing these people any favors by giving them fewer incentives to get an official ID and thus be eligible to participate in these functions of society?  Now it's not the total solution to the problems of the underclass, of course, but I cannot help but wonder if voter ID might prompt some to rejoin society by getting that ID.

Or, put differently, it seems that many opponents of voter ID are quite happy to see people live in squalor, as long as "their" side gets those peoples' votes.
